“Edge of Glory” Lady Gaga (Pentatonix Cover)

Pentatonix (abbreviated PTX) is a five-member American a cappella group from Arlington, Texas, consisting of vocalists Scott Hoying, Mitch Grassi, Kirstin Maldonado, Avi Kaplan, and Kevin Olusola. Characterized by their pop-style arrangements with vocal harmonies, basslines, riffing, percussion and beatboxing, they are widely known for their covers, mostly of modern pop works or Christmas songs, sometimes in the form of medleys, along with original material. Pentatonix formed in 2011 and subsequently won the third season of NBC’s The Sing-Off, receiving $200,000 and a recording contract with Sony Music. When Sony’s Epic Records dropped the group after The Sing-Off, the group formed its YouTube channel, distributing its music through Madison Gate Records, a label owned by Sony Pictures. With over 13 million subscribers and 2.4 billion views, Pentatonix’s YouTube channel is currently the 13th most-subscribed music video channel. The group’s video tribute to Daft Punk had received over 210 million views as of late 2014.
